Benign Skin Lesions 

Seborrheic keratosis

The most common type of skin tumor, seborrheic keratosis, is usually scaly and brown. Sometimes greasy, they vary in size and thickness and sometimes look as if they have been attached or stuck onto the skin. Seborrheic keratosis can show up anywhere on the skin except the palms, soles of feet or any mucous membranes. 

Usually, treatment includes removing the lesion, possibly with cryotherapy, or freezing. Sometimes the appearance of many lesions at once on the trunk or chest may be a sign of cancer. In many cases, they are usually benign. It's best to get a doctor's opinion. 

Dermatosis papulosa nigra

Dermatosis papulosa nigra are hyperkeratotic, hyperpigmented lesions, usually found on the face and neck. They are dark, slightly raised benign spots. Almost 50 percent of the black population has some degree of dermatosis papulosa nigra, and it tends to affects women more regularly than it does men. 

In most cases, they are not removed unless they become a nuisance and are itchy or irritated.
